In response to my inquiry - got the following update from E* customer service:
"Thank you for your e-mail and we apologize for the inconvenience. We recently launched Echo X, our newest satellite addition. Effective May 10, at approximately 1 a.m. MT we will be moving Tulsa local channels from their current location to Echo X at the 110° orbital location. Please be advised that this move may cause programming outages throughout the evening."
So, for Tulsa at least, tonight is the night.
